JET-CONDENSER.

Patented Jan. 30, 1912. Serial No. 466259.

and useful Improvements in Jet-Condens ers, fully described andrepresented in the following specification and the accompanyingdrawings, forming a part of the same. This invention relatesparticularly to jet condensers of the so-called ejector type, theespecial objects being to expose to the steam as large a surface ofcondensing water as possible, and to reduce the loss of energy or powerrequired for water circulation.

In the accompanying drawings forming a part of this specification, thereis shown a condenser of the preferred form einbodying the invention, andthis construction will =3 now be described in detail and the featuresforming the invention then specifically pointed out in the claims.

In the drawings :F igure 1 is a vertical section of the condenser conewith the water and steam distributing devices in eleration. Fig. 2 is avertical section on the line 2 of Fig. 4. Figs. 3 and 4 are sections onrespectively the lines 3 and 4 of Fig. 2. Fig. 5 is a detail section ofa portion of the water distributing ring, showing the adjustment forvarying the condensing water. Fig. 6 is a view similar to Fig. 5 showinga modification. Fig. 7 is a section on the line? of Fig. 6.

Referring to said drawings, A is the condenser cone, B the dischargepipe to which may be attached a barometric tail pipe in a barometriccondenser,C is the exhaust steam inlet, D the condensing water inlet,this condensing water inlet D being formed by a pipe extending downwardcentrally of the condenser. At the lower end of the water inlet pipe Dis the casing E provided with passages for steam and water, and ring Fforming an annular water chamber 12 surrounding the casing E andco-acting'with the bottom edge of the casing to form an annular waterjet. The casing E is supported by a flange connection 10 with the lowerend of pipe D and the ring is connected by bolted flange 11 with thecasing E. .The lower edge 1 of ring F with the outer edge 2 of thebottom of .the casing E formsa narrow opening a, through which theannular water jet is thrown into the condensing chamber from the waterchamber 12, this water chamber 12 being connected by water passages 13with the pipe D, these passages 13 being arranged in an annular seriesabout the casing E. Be-

tween the water passages 13 are the steam passages ll passing verticallythrough the casing E and connecting the steam inlet C with thecondensing chamber inside of the annular water jet from passage a. Steamis also admitted to the condensing chamber outside of and surroundingthe annular water jet through the narrow annular space or passage 15surrounding the distributing apparatus between the ring F and the innerwall of the condenser cone.

The water thrown through the passage a forms complete cone having itsapex in the narrow throat by which the condenser cone connects with thedischarge pipe B, and preferably is out of contact with the inner wallof the condenser cone, as shown, so as to avoid the friction resultingfrom the water moving in contact with the wall at the high velocityrequired in these condensers. Loss of energy or waste of power of thecirculating pump thus avoided. It will be seen," also, that, in thepreferred construction shown, the water passes downward through thecondenser without substantial change of direction which also avoids lossof energy and increases the efficiency of the condenser. The inside ofthis water cone is in contactwith the steam passing through openings 14and the out side of the cone with steam passing through the annularpassage 15, so that a single water jet provides two steam condensingsurfaces, and secures a large condensing surface, and the steam ispreferably distributed about equally on the two surfaces of the annularwater jet, so as to secure the maximu'm condensing effect.

Theedges 1, 2 of the ring F and easing E are inclined so as to throw theannular jet inward in cone form, and for readily adjusting the amount ofwater passing through the condenser, the edges are so formed that theraising or lowering of the ring F decreases or increases the width ofthe passage a, as shown clearly in Fig. 5. The ring F may be adjusted byany suitable means, but as shown is adjusted by putting more or lesspacking 3 between the flange 11 and support oncasing'E to lower or raisethe ring.

In some cases a. larger water surface than is obtainableby annularpassage a may be desired, in which case notches b may be provided on oneor both sides of the annular passage a, as shown in F igsf6 and 7,

- the adjustment of the width of the annular a water chamber,

passage (1 being still retained, if desired.

What is claimed is 1. In a water jet condenser, the combination with acondenser cone, of a vertical injection pipe in the upper part of thecondenser and terminating in a casing separated from the condenser Walland for 'ng nected with the water chamber through which an annular wateret 1s thrown. downward m the condenser c0ne,'a steam inlet .abox e thecasing, opening into the space an annular passage con-- casing andcondenser 'wall, and passages through the casing for theadmission ofsteam from said steam inlet to the space within the annular water jet.
